## Technical Details
- Attack vector: NETWORK via HTTP.
- Exploitability: described as difficult to exploit.
- Privileges: PR:H (high privileges) and UI:N (no user interaction required).
- Impact: successful exploitation can lead to takeover of Oracle Spares Management with C:H/I:H/A:H.
## Affected
- Oracle E-Business Suite — Oracle Spares Management (Internal Operations)
- Affected versions: 12.2.3 to 12.2.15.
## Impact

## Mitigation
1. Apply the vendor’s security patch/updates for the affected Oracle E-Business Suite/Oracle Spares Management versions (per Oracle guidance for CVE-2026-83138).
2. Restrict HTTP network access to Oracle Spares Management to only required sources (reduce exposure for AV:N).
3. Monitor for indicators of compromise and anomalous administrative behavior consistent with a potential takeover attempt (given PR:H and UI:N).
